Abstract
The invention relates to a method for setting an optimum value of a write parameter for use in an optical recording apparatus for writing information on an optical recording medium by means of a radiation beam. The optimum value of a write parameter is found by deriving a plurality of characteristic write power levels (PChar) from a plurality of curve-fitting functions. Each characteristic write power level (PChar) has an associated initial value of the write power level (TV), and the optimum value of the write parameter is found by comparing the characteristic write power levels to the initial write power levels. The invention also relates to an optical recording apparatus for recording information on an optical recording medium, the apparatus having a radiation source for emitting a radiation beam having a controllable value of a write power level for recording information on the recording medium.
